Proc Natl Acad Sci U S A 2019 09 26;116(37):18304-18309. Epub 2019 Aug 26.

School of Engineering, Brown University, Providence, RI 02912;

Graphene-based materials are being developed for a variety of wearable technologies to provide advanced functions that include sensing; temperature regulation; chemical, mechanical, or radiative protection; or energy storage. We hypothesized that graphene films may also offer an additional unanticipated function: mosquito bite protection for light, fiber-based fabrics. Here, we investigate the fundamental interactions between graphene-based films and the globally important mosquito species, , through a combination of live mosquito experiments, needle penetration force measurements, and mathematical modeling of mechanical puncture phenomena.

Measuring Caloric Intake at the Population Level (NOTION): Protocol for an Experimental Study.

JMIR Res Protoc 2019 03 12;8(3):e12116. Epub 2019 Mar 12.

Department of Cardiac, Thoracic and Vascular Sciences, University of Padova, Padova, Italy.

Background: The monitoring of caloric intake is an important challenge for the maintenance of individual and public health. The instruments used so far for dietary monitoring (eg, food frequency questionnaires, food diaries, and telephone interviews) are inexpensive and easy to implement but show important inaccuracies. Alternative methods based on wearable devices and wrist accelerometers have been proposed, yet they have limited accuracy in predicting caloric intake because analytics are usually not well suited to manage the massive sets of data generated from these types of devices.

Not all electric shark deterrents are made equal: Effects of a commercial electric anklet deterrent on white shark behaviour.

PLoS One 2019 11;14(3):e0212851. Epub 2019 Mar 11.

The UWA Oceans Institute and the Oceans Graduate School, The University of Western Australia, Crawley, Western Australia, Australia.

Personal shark deterrents offer the potential of a non-lethal solution to protect individuals from negative interactions with sharks, but the claims of effectiveness of most deterrents are based on theory rather than robust testing of the devices themselves. Therefore, there is a clear need for thorough testing of commercially available shark deterrents to provide the public with information on their effectiveness. Using a modified stereo-camera system, we quantified behavioural interactions between Carcharodon carcharias (white sharks) and a baited target in the presence of a commercially available electric anklet shark deterrent, the Electronic Shark Defense System (ESDS).

Authors:
Lucia Seminara

Sensors (Basel) 2018 Feb 3;18(2). Epub 2018 Feb 3.

Department of Electrical, Electronics and Telecommunication Engineering and Naval Architecture, via Opera Pia 11A, University of Genoa, Genoa 16145, Italy.

The reference electronic skin is a sensor array based on PVDF (Polyvinylidene fluoride) piezoelectric polymers, coupled to a rigid substrate and covered by an elastomer layer. It is first evaluated how a distributed normal force (Hertzian distribution) is transmitted to an extended PVDF sensor through the elastomer layer. A simplified approach based on Boussinesq's half-space assumption is used to get a qualitative picture and extensive FEM simulations allow determination of the quantitative response for the actual finite elastomer layer.
